Mexico City, Mexico, October 27, 2023— Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ: OMAB; BMV: OMA), today reported its unaudited, consolidated financial and operating results for the third quarter 2023 (3Q23).

Total passenger traffic reached 7.4 million passengers, an increase of 18.6% as compared to 3Q22. During the quarter, of total traffic, 88.8% was domestic and 11.2% was international.

Domestic passenger traffic increased 18.1%, compared to 3Q22, while international traffic increased 22.8%.

The airports with the largest passenger traffic growth in volume terms as compared to 3Q22, were:

The commercial space occupancy rate in the passenger terminals was 94.7% as of September 30, 2023.

Aeronautical revenues increased 31.0% mainly due to an increase in passenger traffic, compared to 3Q22, as well as increases in aeronautical tariffs during the first quarter of the current year.

Commercial revenues increased 23.6%. The line items with the largest increases were:

Diversification revenues increased 8.3%, mainly due to higher revenues from Hotel Services.

Construction revenues represent the value of improvements to concessioned assets. They are equal to construction costs and generate neither a gain nor a loss. Construction revenues and costs are determined based on the advance in the execution of projects in accordance with the airports’ Master Development Programs (MDP), and variations depend on the rate of project execution.

The sum of cost of airport services and general and administrative expenses (G&A) increased 2.8%, mainly due to higher minor maintenance, contracted services and basic services costs, partially offset by lower payroll costs.

The major maintenance provision was Ps.94.8 million. The outstanding balance of the maintenance provision as of September 30, 2023 was Ps.2,159 million.

The airport concession tax was Ps.151 million and the technical assistance fee was Ps.66.9 million.

Financing Expense was Ps.272 million, compared to Ps.219 million during 3Q22. The increase was mainly due to a higher interest expense as a result of a higher level of indebtedness and an increase in financing costs.

Consolidated net income in the quarter was Ps.1,414 million, an increase of 28.4%.

Earnings per share, based on net income of the controlling interest was Ps.3.65, and earnings per ADS was US$1.66. Each ADS represents eight Series B shares.

In 3Q23, capital investments and major maintenance works in the MDPs and strategic investments totaled Ps.964 million, comprised of Ps.719 million in improvements to concessioned assets, Ps.105 million in major maintenance, Ps.139 million in strategic investments and Ps.1 million in other concepts.

During 3Q23, cash flows from operating activities generated cash of Ps.1,498 million.

Investing activities used cash for Ps.505 million in the third quarter. Financing activities reflect mainly the second tranche of the ordinary dividend payment of Ps.500 million, resulting in a net cash outflow of Ps.798 million.

The net increase in cash resulting from operating, investing and financing activities in 3Q23 was Ps.195 million. This, combined with the positive effect of changes in the value of cash of Ps.19.1 million, resulted in a Cash and Cash Equivalents balance as of September 30, 2023 of Ps.2,220 million.

Unless stated otherwise, all comparisons of operating or financial results are made with respect to the comparable period of 2022. The exchange rates used to convert foreign currency amounts were Ps.20.1927 as of September 30, 2022, Ps.19.4715 as of December 31, 2022 and Ps.17.6195 as of September 30, 2023.

Construction revenue, construction cost: IFRIC 12 “Service Concession Arrangements” addresses how service concession operators should account for the obligations they undertake and rights they receive in service concession arrangements. The concession contracts for each of OMA’s airport subsidiaries establishes that the concessionaire is obligated to carry out improvements to the infrastructure transferred in exchange for the rights over the concession granted by the Federal Government. The latter will receive all the assets at the end of the concession period. As a result, the concessionaire should recognize, using the percentage of completion method, the revenues and costs associated with the improvements to the concessioned assets. The amount of the revenues and costs so recognized should be the price that the concessionaire pays or would pay in an arm’s length transaction for the execution of the works or the purchase of machinery and equipment, with no profit recognized for the construction or improvement. The application of IFRIC 12 does not affect operating income, net income, or EBITDA, but does affect calculations of margins based on total revenues.

Capital investments: includes investments in fixed assets (including investments in land, machinery, and equipment) and improvements to concessioned properties under the Master Development Plan (MDP) plus strategic investments.

Strategic Investments: Refers only to those capital investments additional to the Master Development Program.

Passengers and Terminal passengers: All references to passenger traffic volumes are to Terminal passengers, which includes passengers on the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit. The definition of terminal passengers of OMA may differ from the definition utilized by its shareholder VINCI Airports.

Adjusted EBITDA and Adjusted EBITDA margin: OMA defines Adjusted EBITDA as EBITDA less construction revenue plus construction expense and maintenance provision. We calculate the Adjusted EBITDA margin as Adjusted EBITDA divided by the sum of aeronautical revenue and non-aeronautical revenue. Construction revenue and construction cost do not affect cash flow generation and the maintenance provision corresponds to capital investments. OMA defines EBITDA as net income minus net comprehensive financing income, taxes, and depreciation and amortization. Neither Adjusted EBITDA nor EBITDA should be considered as an alternative to net income as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. It should be noted that neither Adjusted EBITDA nor EBITDA is defined under IFRS, and may be calculated differently by different companies.
